Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool lists breakpoints but doesn't describe what a breakpoint entails in this context, how results are returned (e.g., format, pagination), or any side effects (e.g., if it's read-only, requires specific permissions). This leaves significant gaps for a tool with no annotation coverage.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is appropriately sized and front-loaded, with the core purpose stated first in a single sentence, followed by parameter details. There's no unnecessary verbosity, though the structure could be slightly improved by integrating the 'Args' section more seamlessly.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the lack of annotations and output schema, the description is incomplete. It doesn't explain what breakpoints are in this context, how results are structured, or any behavioral traits (e.g., read-only nature, error conditions). For a tool with no structured data support, this leaves the agent under-informed.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description includes an 'Args' section that documents the single parameter 'session_id', adding meaning beyond the input schema, which has 0% description coverage. However, it doesn't explain what a session ID is, how to obtain it, or its format, leaving some semantic gaps despite compensating for the low schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('List all breakpoints') and the scope ('in the session'), which is a specific verb+resource combination. However, it doesn't explicitly differentiate from sibling tools like 'list_watchpoints' or 'list_symbols', which serve similar listing functions for different resource types.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing an active session), exclusions, or comparisons to similar listing tools like 'list_watchpoints' or 'list_symbols', leaving the agent to infer usage context.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
